How it works
The valve draws a pocket of air into the top of the tank. Water passes through the air, which oxidizes iron, manganese and hydrogen sulfide into particles, and the media bed filters them out. Every day the valve backwashes the bed, sends the trapped particles to drain and refreshes the air pocket.
Media benefits
- Removes iron, manganese and hydrogen sulfide (rotten-egg smell) in one tank
- Handles high flow rates in a compact tank
- Long media life
- Backwashes the trapped particles to drain automatically
- Air injection oxidizes iron, manganese and sulfur with plain air, so no chemicals or chlorine are added

Performance Profile
Katalox-Light® offers low pressure loss, high service and flow rates, and high bed loadings with reduced backwash frequency. It can run at up to 12 gpm per square foot in a single vessel and needs only 5 to 10 minutes of backwash at 5.5 gpm per square foot. The 12-inch tank adds the flow capacity larger homes need to serve multiple fixtures at once. Supplied by Water Softener Plus and installed at the point of entry, this system handles complex well-water chemistry efficiently — add your chosen adapters to complete the installation.
Plan the installation at the point of entry so all incoming water is treated before reaching fixtures, the water heater, or any downstream softener. The Katalox-Light media bed benefits from a stable backwash flow, so size your drain line accordingly and ensure adequate water pressure for the periodic rinse. Because the media handles several contaminants at once, this single system can often replace a more complicated multi-stage setup, simplifying both the install and long-term upkeep.
From the control valve to the media bed, every part of this Water Softener Plus system is selected to work together reliably, so once it is installed and dialed in you can simply enjoy the improvement in your water without thinking about it.
